As much as I hate thread necromancy and how annoying that is in general forum common sense, today I did eventually find it through random follow-the-old-linkpages which reminded me toward this thread here.
- It dates to January 1997
- It DIDN'T have the phantom train as the background BUT!! It did have phantom train startup and shutdown sounds as I have mentioned.
- The busy cursor is animated and turns into an imp

- Blue as heck!
I think I can sleep easier now
EDIT: Unfortunately sometimes robots.txt gets detected from the squatter of the domain and causes the link to not display. Try another day if it doesn't.
EDIT2: Andrew Vestal ran the original Unofficial Squaresoft page (where those themes were hosted) so maybe there was a newer FF3DT zip with the phantom train lurking on one of his backups. but that's probably asking for too much for something rather trivial. The archive only goes back to April 1997 at the latest. His own backup only goes up to 1996 and lacks the programs and themes.
